In the north-east of Campania Felix, separated from the Campania Apennines by the valley of the Medio Volturno, the massif of the Trebulani Mountains rises, also known as the Colli Caprensi.
For the ancients, it was the river of the myth, which gave forgetfulness to whoever drunk its water.
It rises at the foot of Mounts Trebulani, at 86 meters above sea level, in the territory of Calvi Risorta.
It is an artificial lake, created in the 1960s to power the electricity station of Capriati al Volturno.
Although its name derives from the Oscan word tifata, which means holm oak, Mount Tifata is largely barren, except for the woods surrounding the northern side.
The longest river of Southern Italy with its 175 kilometres rises in Molise, at Rocchetta a Volturno and runs for a long way in the Apennine region, of which, after the Ponte 25 archi, marks the border with Campania.
Older than Vesuvius. It is among the biggest of Italy, but extinct since fifty thousand years ago. The Roccamonfina volcano rises isolated between the Aurunci Mountains, in Lazio, and in Campania Felix the plain of Garigliano and the Massico massif, separating it from the Tyrrhenian Sea.
